Caution for the safety during servicing 1. Do not allow the customer to repair the product. ☞ The person may be injured or the product life may be shortened. 2. Execute A/S after unplugging the power supply unit. ☞ Be care of the electric shock. 3. Do not plug several plugs in the same outlet. ☞ It may cause the fire due to overheat. 4. Check the damage, pressing or burning of the power plug or outlet. ☞ Replace it promptly if it has problem.(may cause the electric shock or fire) 5.

2. Safety Devices ※ We adapt 5 safety devices for users to use this wash machine safely. 1) Balancing device (ASSY-Main PCB) → When the laundry is out of balance, to prevent the noises and vibrations, the unbalance detecting sensor helps the laundry laid even and continue the dehydating process.

5. Main function 4) Power-out compensation function ● If power is out on selected process, the process before power out is stored to EEPROM, once power is back the process before power out continues. ● When power is back, washing process starts from the process at the point of the power out, rinse/drain process starts from the initial process.
5. Main function 6) Fuzzy washing function ( weight-sensing) ☞ After finishing initial water supply, when the fall of the water level needs supplementary water supply, Sensing function perceives the weght with the supplementary water supply numbers and starts to work.

7. General Error Function When an error occurs, this function starts to keep generating error melody sounds and displays error indicators as shown in the followings per corresponding error by blinking in 0.5sec interval until the error status is completely cleared out. In this case, all the driving devices are turned off until the error is cleared out. 1. WATER SUPPLY ERROR - Display shows such as fig.
7. General Error Function - If the same signal as the above table is detected for more than 5 seconds, it is a PRESSURE S/W Error. - When the error occurs, water drain pump will operate for 3 min. and then turn off the water drain pump. Then the display shows fig. 8 indicating a pressure s/w error indicator. fig. 8 8. ABNORMAL WATER TEMPERATURE ERROR - In case the water temperature is 50∞C or more in Delicate and Wool course.
8. Trouble Diagnosis - As the micom wash machine is configured of the complicate structure, there might be the service call. Below information is prepared for exact trouble diagnosis and suitable repair guide. Caution for the Repair and Replacement Please follow below instruction for the trouble diagnosis and parts replacement.
8-1. Trouble Diagnosis No Item Cause and treatment The power is not supplied - Is the PCB connector connected well? - Is the voltage normal? - Is the power supply plug connected well? - Is the noise filter connected well? - Is the secondary output of the power supply transformation normal? - Is the fuse disconnected? (option) ï If above points are not found, the PCB assembly is out of order. Replace it. The water is not supplied.
